You can still get a .280 in a Remington Mountain rifle. They only sell the laminated stainless version brand new, but there are some blued/walnut used ones kicking around. I have 2 and love'em. I got realy lucky last September. I went in to WSS looking to get a .30-06 in the Mtn rifle LSS. They had one, but there was something about that rifle that made me pass on it. I don't remember what. Then the sales guy said that he recently found in the back a blued/walnut Mtn rifle in .280 with the DM. It was brand new, never out of the box. Remington hasn't been making these for several years; only the LSS versions. So, even though I already had a .280 in a Mtn Rifle, I bought it anyway. Then in October I went back and found a .30-06 in LSS that I did like.
The m700 mountain rifles have a bad reputation for being weak in the acuraccy department, but out of the 3 I own, none won't do 1" or better at 100 yards... when I find the right load for it.
